How can select a cell in the first time clicking on it

I am implementing a grid with two Textbox cells: cell #1 is used to select (does not edit) and cell #2 is used to edit. Could you please help me to anwser questions below: 1) How can select all the text in editable cell in the first time clicking on it? 2) for Cell #1, How can it always select all text when cliking on it? thanks for your suporting!

I am not sure hwat the difference is between your requests 1 and 2. But you can cause all the text to be selected when you click on a cell by setting this property. this.gridDisplay.ActivateCurrentCellBehavior = GridCellActivateAction.SelectAll;

Thank you! For question #2, when click many times on cell, how is the text (on the cell) still selected (not select one word of text) ?

If you want to selectall on a doubleclick of an active cell (instead of selecting a word), handle the CurrentCellControlDoubleClick event. private void gridControl1_CurrentCellControlDoubleClick(object sender, ControlEventArgs e) { GridTextBoxControl tb = e.Control as GridTextBoxControl; if(tb != null) { tb.SelectAll(); } }

When using tb.SelectAll() or this.dgrTemplateManagement.ActivateCurrentCellBehavior = Syncfusion.Windows.Forms.Grid.GridCellActivateAction.SelectAll, How to show the text at the beginning of textBox? Thanks!

You can try handling the CurrentCellControlGotFocus event.

private void gridDataBoundGrid1_CurrentCellControlGotFocus(object sender, ControlEventArgs e)
{
	GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell;
	GridTextBoxControl tb = cc.Renderer.Control as GridTextBoxControl;
	if(tb != null)
	{
		tb.SelectionStart = tb.Text.Length;
		tb.SelectionLength = 0;
		SendKeys.Send("+({HOME})");
	}
}
